10.
Two equal sides of a triangle are each 5 meters less than twice the third side. If the
perimeter of the triangle is 55 meters, find the length of its sides?​

Answer 1

p=55

equal side(e) =(2×unequal side(u)) +5

equal side +equal side+unequal side=55

2e+u=55

2×[(2×u)+5]+u=55

4u+10+u=55

5u=45

u=9

e=2×9+5

e=18+5

e=23
